Genome Evolution
Genomic evolution is the process that changes the structure (sequence) or size of a genome over time.
The study of genome evolution involves multiple fields such as structural analysis of the genome, the study of genomic parasites, gene and ancient genome duplications, polyploidy, and comparative genomics. Evolutionary biologists are interested in five specific questions in regards to evolution of the genome, these are:
- How did the genome evolve into its current size?
- What is the content within the genome, is it mostly junk or not?
- What is the distribution of genes within a genome?
- What is the composition of the nucleotides within the genome?
- How does translation of the genetic code evolve?

Famous quotes containing the word evolution:
“Like Freud, Jung believes that the human mind contains archaic remnants, residues of the long history and evolution of mankind. In the unconscious, primordial “universally human images” lie dormant. Those primordial images are the most ancient, universal and “deep” thoughts of mankind. Since they embody feelings as much as thought, they are properly “thought feelings.” Where Freud postulates a mass psyche, Jung postulates a collective psyche.”
—Patrick Mullahy (b. 1912)
